Description

Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to an interlocking composite panel. Background Technology

[0002] Composite floor slabs are prefabricated monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. They offer good overall integrity, with smooth upper and lower surfaces facilitating finishing. Suitable for high-rise buildings and large-span buildings requiring high overall rigidity, composite floor slabs utilize precast slabs as both a structural component and a permanent formwork for the cast-in-place reinforced concrete composite layer. Horizontal equipment pipelines can be laid within the cast-in-place composite layer. Composite floor slabs offer excellent integrity and high rigidity, saving on formwork, and their smooth upper and lower surfaces facilitate finishing, making them ideal for high-rise buildings and large-span buildings requiring high overall rigidity.

[0003] To improve work efficiency, an overlapping method is adopted for connection. However, the current overlapping method of composite slabs uses steel bars for connection. The lack of overlapping structure between composite slabs reduces the convenience of connection. When overlapping, it is difficult to ensure the stability between composite slabs by relying solely on the reserved steel bars. During placement, the reserved steel bars are also easily bent, which impairs the strength of the floor after pouring and reduces stability. Therefore, we propose an interlocking composite slab. Utility Model Content

[0004] The purpose of this utility model is to provide an interlocking composite slab to solve the problem mentioned in the background art that the composite slabs lack an overlapping structure and that it is difficult to ensure the stability of the composite slabs by relying solely on pre-reserved steel bars.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite panel, comprising a composite panel body and a lower insert plate, wherein the lower insert plate is fixedly connected to the right side wall of the composite panel body, right-angle steel bars are installed in the inner cavity of the composite panel body and arranged sequentially from front to back, straight steel bars are installed in the inner cavity of the composite panel body and arranged sequentially from front to back, truss steel bars are fixedly connected to the top of the composite panel body and arranged sequentially from front to back, a first threaded groove is opened on the top right side of the lower insert plate and arranged sequentially from front to back, an upper insert plate is fixedly connected to the left side wall of the composite panel body, a trapezoidal groove is opened on the top of the upper insert plate, a second threaded groove is opened at the bottom of the inner cavity of the trapezoidal groove, and a connecting bolt is screwed into the inner cavity of the second threaded groove.

[0006] As a further description of the above technical solution: the right-angle steel bar penetrates the inner cavity of the composite slab body and extends to the inner cavities of the lower panel and the upper panel.

The inner cavity of the composite slab body 100 is equipped with straight steel bars 111, which are arranged sequentially from front to back. The straight steel bars 111 are used to reinforce the upper panel 220 and the lower panel 200. The top of the composite slab body 100 is fixedly connected with truss steel bars 120, which are arranged sequentially from front to back. The truss steel bars 120 are used to improve the structural strength of the composite slab body 100 and enable the composite slab body 100 to be lifted by lifting equipment.

[0025] Please refer to it again. Figure 1-5 The lower panel 200 is fixedly connected to the right side wall of the composite plate body 100. The top right side of the lower panel 200 has a first screw groove 210, which is arranged sequentially from front to back. The first screw groove 210 is used to cooperate with the connecting bolt 223 to connect and fix the upper panel 220 and the lower panel 200. The left side wall of the composite plate body 100 is fixedly connected to the upper panel 220. The top of the upper panel 220 has a trapezoidal groove 221, which is used to install the second screw groove 222. The bottom of the inner cavity of the trapezoidal groove 221 has a second screw groove 222, which is used to install the connecting bolt 223. The inner cavity of the second screw groove 222 is screwed with the connecting bolt 223, which is used to cooperate with the first screw groove 210 to connect and fix the upper panel 220 and the lower panel 200.

[0026] In summary, the upper panel 220 and the lower panel 200 are fitted together by the cooperation of the positioning rod 212 and the positioning through groove 230. The connecting bolt 223 is moved into the first screw groove 210 by rotating the connecting bolt 223, thereby completing the fixation of the upper panel 220 and the lower panel 200, and thus completing the connection between the composite plate bodies 100. The operation is simple and convenient, and the connection convenience is improved.

[0027] Please refer to it again.

[0028] Please refer to it again. Figure 1 The top of the composite slab body 100 has a groove 121, which is arranged sequentially from front to back. The groove 121 is V-shaped and is used to increase the adhesion of the composite slab body 100 to the poured cement.

[0029] Please refer to it again. Figure 3-5 The dimensions of the lower panel 200 and the upper panel 220 are matched so that the lower panel 200 and the upper panel 220 can fit together.

[0030] Please refer to it again. Figure 1-3 The lower panel 200 has baffles 211 fixedly connected to both the front and rear sides of the top. The baffles 211 are used to limit and fix the upper panel 220 to prevent the upper panel 220 from shifting due to external forces.

[0031] Please refer to it again. Figure 1-5 The lower panel 200 has positioning rods 212 fixedly connected to the front and rear sides of the top, and the upper panel 220 has positioning slots 230 on the front and rear sides of the top. The positioning rods 212 are used to cooperate with the positioning slots 230 to position the upper panel 220 and the lower panel 200, and at the same time, they can limit the position and prevent the upper panel 220 from shifting due to external forces.

[0032] In summary, by aligning the positioning rod 212 with the positioning through groove 230, the upper panel 220 and the lower panel 200 are fitted together. By rotating the connecting bolt 223, the connecting bolt 223 is moved into the first threaded groove 210, thereby fixing the upper panel 220 and the lower panel 200. At the same time, the baffle 211 clamps the upper panel 220 to prevent positional displacement. The positioning rod 212 and the positioning through groove 230 cooperate to limit and fix the upper panel 220 and the lower panel 200, preventing positional displacement caused by external forces, and ensuring that the upper panel 220 and the lower panel 200 fit tightly together, thus improving stability.

[0033] In practical use, those skilled in the art use the positioning rod 212 and the positioning slot 230 to engage the upper panel 220 and the lower panel 200. By rotating the connecting bolt 223, the connecting bolt 223 is moved into the first threaded groove 210, thereby fixing the upper panel 220 and the lower panel 200, thus completing the connection between the composite plate bodies 100. Aligning the positioning rod 212 with the positioning slot 230 allows the upper panel 220 and the lower panel 200 to engage. By rotating the connecting bolt 223, the connecting bolt 223 is moved into the first screw groove 210, thereby fixing the upper panel 220 and the lower panel 200. At the same time, the baffle 211 clamps the upper panel 220 to prevent positional displacement. The positioning rod 212 and the positioning through groove 230 cooperate to limit and fix the upper panel 220 and the lower panel 200, preventing positional displacement caused by external forces, so that the upper panel 220 and the lower panel 200 fit tightly together.
